Thank Anthony, for now it allow to display some stats if I want too, which
are pretty good... For further performance measure I can also just use the
profiler...
My main requirement was to be able to display end user some performance
stats...
Some improvement here (sorry BS 2.3) :
{{if auth.has_membership('admin'):}}
<div class="row">
<button class="btn btn-small"
onclick="$('#loading_stats').toggle();">Loading stats...</button>
<br>
<br>
<div id="loading_stats" class="well span4" style="display: none;">
<strong>Loading statistics</strong>
</div>
</div>
<script type="text/javascript">
function onLoad() {
var now = new Date().getTime();
var network_latency = performance.timing.responseEnd -
performance.timing.fetchStart
var load_page_received = now - performance.timing.responseEnd
var total_page_load = now - performance.timing.navigationStart
$( "<p>Network latency: " + network_latency + " ms</p>"
).appendTo( "#loading_stats" );
$( "<p>Loading page once everything is recieved from server: "
+ load_page_received + " ms</p>" ).appendTo( "#loading_stats" );
$( "<p>Whole process of navigation and page load: " +
total_page_load + " ms</p>" ).appendTo( "#loading_stats" );
}
</script>
{{pass}}
Forget to mention you have to put this in the layout :
<body {{if auth.has_membership('admin'):}}onload="onLoad()"{{pass}}>
